A system for distributing a fluid in a vehicle, comprising: a plurality n of independent fluid ejection devices; a plurality n1 of distributors, each having an inlet, a first outlet and a second outlet and being configured to establish a fluid connection either between the inlet and the first outlet or between the inlet and the second outlet; the inlet of a first distributor being connected to a pump connected to a fluid reservoir; each independent ejection device being connected to an outlet of a distributor; at least one outlet of a distributor being connected to the inlet of a subsequent distributor.

A flow control valve assembly has at least one manifold having an inlet flow port, an outlet flow port, and a flow channel provided there between, the flow channel having an inlet chamber, a variable area chamber and an outlet chamber, with fluid flowing from the inlet flow port to the inlet chamber, the variable area chamber and the outlet chamber, in that order, before exiting the outlet flow port. The flow control valve assembly further includes a float assembly having a float extending through the flow channel and which is limited for its movement inside the variable area chamber, a connecting rod extending through the flow channel and which has an upper end that is connected to the float and a lower end that is connected to a magnet. A measuring device is positioned outside the fluid chamber at the bottom of the at least one manifold, and spaced apart from the magnet.

A solenoid assembly is provided including a housing having a cavity; an enclosure mounted on the housing; an electricity conducting coil surrounding a tubular passageway traversed by a vertical axis, the coil arranged within the cavity; an armature assembly moveable from a first to a second position being forced by a temporary magnetization; a circuit board oriented perpendicular to the vertical axis and at least partially covered underneath the enclosure, the board including a logic circuit and a power regulating circuit.

An actuator for controlling a fluid path includes an actuator having a seat part, either a fluid-valve membrane or a movable part, and a magnetorheological elastomer that changes form when a magnetic field changes. This causes the path to open or close.

A fluidic valve device intended to be arranged in a fluidic circuit, the device notably including a first switching assembly including a first compartment defining a first internal space and a first permanent magnet arranged with the freedom to slide in the first internal space, a second switching assembly including a second compartment defining a second internal space and a second permanent magnet arranged with the freedom to slide in the second internal space, the first permanent magnet and the second permanent magnet being arranged relative to one another in such a way as to be in a first state of magnetic interaction, making it possible to obtain a first stable mechanical configuration or in a second state of magnetic interaction, it possible to obtain a second stable mechanical configuration.

A valve includes an electrodynamic actuator which has a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable coil which is arranged in the magnetic field and is firmly coupled to a coil carrier. The control element is movable between at least two defined positions. There are provided permanent-magnetically interacting holding force which retain the control element in at least one of the defined positions, even when the coil is currentless.

The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

The present invention discloses a movable valve core and an electromagnetic valve comprising the same. The movable valve core, comprising a cylindrical core body (1) defining a central axis, a leading head (2) fixed to the core body (1) removably, wherein a water-proof valve membrane (3) sandwiched between the core body (1) and the leading head (2), wherein a mounting hole (4) is axially formed in the core body (1), and a connector (5) for projecting into the mounting hole (4) extends axially from the bottom of the leading head (2), and the connector (5) is fixed into the mounting hole (4). The connector (5) is provided with an outer thread (6), and the leading head (2) is screwed into the mounting hole (4).

The present invention provides a rocker valve comprising a valve body including first and second fluid ports and a rocker valve mechanism in the valve body. The mechanism comprises a single pivot arm rotatable relative to the valve body, and first and second plungers pivotally fixed to the single pivot arm. The second plunger acts in opposition to the first plunger when the single pivot arm is pivoted relative to the valve body. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports. The flexible seal member has a first sealing region attached to the first plunger and a second sealing region attached to the second plunger and is movable by the first and second plungers between a first position in which the first fluid ports is closed by the first sealing region, and a second position in which the second fluid port is closed by the second sealing region. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member.
